NEW YORK, ASSIGNOR T SYRAGUSE WASHING MACHINE CORPORATION, OF SYRACUSE,NEW YORK, A CORPORATION OF DELAWARE IRONING MACHINE Application filedAugust 115,

This invention relates to a new and improved ironer.

It has been Vfound that as, for example, collars, better and quickerobtained in the ironing operation if the article is sent between theroll and the shoe first in one direction and then in another direction,and the mainl object of my invention is to provide an ironer in which bemade to rotate in with certain articles either direction.'

Another yobject is to provide a means whereby the roll is permitted toremain at rest while the ironing shoe is operated, which is a veryconvenient arrangement when it is desired to press articles on theironer.

Other objects and advantages relate to the size, shape and arrangementof parts, all as will more fully appear from the following descriptiontaken in connection with the accompanying drawings in which Figure 1 isa top plan view of my improved ironer.

bearingl 6 is positioned in the outer end of tube 4.

A drive shaft is journaled in bearings 5 and 6 with its outer endextending beyond bearing 6. The construction of the inner end of shaft 7will be hereinafter described.

An ironing roll 8 having the usual fabric covering 9 carries adjacentits inner en d an internal plate lprovided at its central portion with abearing' member 11 in which tube 4 is positioned.

The outer end of roll 8 carries a similar plate 12 having a bearingmember 13 in which the outer end of tube 4 is positioned. On the outerend of shaft 7 is secured, as by a pin 14, an offset arm 15 which hasits outer end secured to plate 12, as by a pin 16, so that the rotarymovement of shaft 7 will be communicated to roll 8.

A second laterally extending boss 17 has positioned therein in parallelrelation to tube 4 a second supporting tube 18. The outer end of tube 18is supported in a saddlemember 19.

A shaft 20 extends through tube 18 with its inner end extending beyondtube 18 into gear casing 2. The outer end of shaft 20 extends beyond theouter end of the tube 18 vand has secured thereto, as by a pin 21, anironing shoe support 22.

AOn the upper end of support 22 is pivotally mounted on a p in 23 a yoke24. An ironing shoe 25 having positioned therein the usual heating unit26 is secured -to yoke24, as by bolts 27, andhas a lead 26 so that itmay be connected to a source of potential.

Yoke 24 is so designed in relation to the support as to limit thedownward pivotal movement of yoke 24 when shoe 25 is out of contact withroll 8.

An axially movable shaft 28 has one end journaled in a bearing 29 on oneside of casing 2 and has the other end journaled in the bearing 3() inthe opposite side of casing 2. As indicated in dotted lines in Figure3., bearing 30 has its inner face formed into a cam surface 31 for apurpose hereinafter to be described.

-A motor 32 is secured to casing 2 and has a lead 32 ,so that it may beconnected to a by a pin 37, is a 42 carries a depending lu source ofpotential. The armature shaft 33 of the motor 32 extends into casing 2with its axis normal to the axis of shaft 28.

The inner end of armature shaft 33 carries Worm 34. A worm gear 35 ismounted on shaft 28 and is in mesh with worm 34. lVorm gear 35 has alaterally extending hub 36.

Secured to the hub 36 of worm gear 35, as

circular toothed clutch member 38. Ad'aeent clutch member 38 and keyedto sha t28, as by a key 39, is a member 40 having a circular portion 4leccentrically positioned with relation to shaft 28.

The keyway in member 40 is elongated to permit the movement therein ofkey 39, key 39 being rigidly secured in shaft 28.

eferring to Figure 7, a dog 42 is pivotally mounted on member 40 on apivot pin 43. Dog

44 adapted to register with one of a plu ty of circumferentially spacedslots 45 in member 38.

Referring to Figure 8, a plate 46 is also pivotally mounted on member 40on pivot pin 43 and conforms in shape and position approximately to dog42.

One end of plate 46 is bent,as shown at -ain Figure l0, which bentportion is in spaced relation to dog 42.

A s iral spring 47 is interposed between the end of) plate 46 and dog42. The upper edge of plate 46 is also bent outwardly, as shown at -bonFigure 10, above the upper end ofdog 42 to limit the upward movement of35 dog 42 in relation to plate 46 under the action of spring 47.

spiral spring 48 has one end secured to member 40, as by a pin 49, andhas the other end secured to end of plate 46 to normally .-urge plate46, carrying with it dog 42, about the pivot 43 to bring the lug 44 intoengagement with a slot 45 in clutching member 38.

For the purpose of holding dog 42 out of engagement with clutch member38 so that member 40 may be at rest, I provide a member 50 having itsupper end secured to the inner end of a rock shaft 51 mounted in casino'2.

t (5)11 the outer end of shaft 51 is provided a hand lever 52 to providea convenient means for manually rocking shaft 5l.

The lower end of the member 50 is adapted to be moved into and out ofthe path of movement of plate 46 and dog 42 and is so dimensioned thatwhen it is in such path of movement plate 46 and dog 42 will be held insuch a position that the lug 44 will be out of registration with theclutch member 38.

When the member 5() is in the path of movement of plate 46 and thelatter is brought into contact therewith, the spring 47 will becompressed and the dog 42 will be raised to carry lug 44 out ofregistration with clutch member 38.

The spring 47 will then expand, moving rotatablyn movement of plate 46and the dog 42 further about the pivot 43 to p0- sition the lug 44 inspaced relation to the clutch member 38 so that there will be nopossibility of the two contacting while the clutch member 38 continuesto rotate. This dog 42 takes place when the end of plate 46 to which thespring 48 is attached contacts with the member 50.

When the opposite end of plate 46 contacts with member 50, the samemovement of parts will take place due to the fact that such end of plate46 is held against further movement and this will cause plate 46 to bemoved about its pivot to compress spring 47 and move lug 44 out ofregistration with clutch member 38.

Spring 47 will then expand to further move dog 38 about its pivot tocarry lug 44 to a position in spaced relation to clutch member 38.

The face of gear 35 opposite to that which carries the hub 36 isprovided with a plurality of circumferentially spaced female clutchmembers which carries the clutch members 53 is rotatably mounted onsleeve 28 a gear 54 carrying a plurality of male clutch members 55adapted to co-act with the clutch members 53 in gear 35.

Adjacent the face of gear 54 which carries the clutch members 55, theshaft 28 is formed with an annular groove 56 in which is positioned acircular disk 57 which bears against the face of sleeve 28. n

Encircling shaft 28 and boss in casing 2 is a spiral spring 58 whichnormally urges sleeve 28 and gear 54 into clutching engagement with gear35.

Referring to Figures 3, 4 and 5, the inner end of shaft 7 carries acollar 59 and has a reducedthreaded end 60. l

The inner end of shaft 7 is slotted, as shown at con Figure 5, and hasan internally extending aperture 61 extending from the end of shaft 7beyond collar 59.

A gear 62 is rotatably mounted on shaft 7 abutting against the innerface of collar 59. Gear 62 has a plurality of circumferentially spacedfemale clutch members 63 positioned outside of the periphery of collar59.

A second gear 64 is rotatably mounted on shaft 7, abutting against theouter face of eollar 59. Gear 64 has on its face towards gear 62 aplurality of circumferentially spaced female clutch members 65positioned outside of the periphery of collar 59. Gear 64 is heldagainst axial displacement by a nut 66 on the threaded end 60 of shaft7. Gear 64 is in mesh with gear 54. Gear 62 is in mesh with gear 67carried on a stub shaft 68. Gear 67 is in mesh with gear 54. Therotation .of gear 54 will cause gear 64 to be rotated in one directionwhereas the rotation of gear 54 through gear 67 will cause the rotationof gear 62 in the opposite direction.

53. Adjacent the face of gear 35 v A shaft 69 is slidably mounted in theapertured end of shaft 7 and carries on its forward end a double maleclutch member 70 which is positioned in slot c and extends outwardlytherefrom on both sides of collar 59.

Member 70 carries on one end a pin 71 which extends outwardly from bothsides of member 70 and which is adapted to enter an aperture 63 in gear62, or an aperture 65 in gear 64 depending on the direction of the axialmovement of shaft 69.

The other end of member 70 carries a similar pin 72 which is alsoadapted to enter either an aperture 63 or an aperture 65. The relationof parts is such that the member 7 0 may be positioned between ears 62and 64 with the pins 71 and 72 out of registration with both apertures63 and 65.

The outer end of shaft 69 is enlarged and is provided with an annulargroove 73 in which is positioned a shifting fork 74 on the lower end ofa lever 7 5. Lever 75 is pivoted at 76 to casing 2, the upper end oflever 75 extending upwardly through an aperture 77 in the top of casing2.

A coil spring 78 has one end secured to the casing 2 and has the otherend secured to a shoulder 79 on lever 7 5. The relation of parts is suchthat when the upper end of the lever 75 is moved in one direction,lspring 79 will cross pivot 76 and tend to hold lever 75 in thatposition. Similarly, when the upper end of lever 75 is moved, thegreatest distance in the opposite direction, spring 79 will again crosspivot 76 and tend to hold lever 75 in that position. v

As shown in Figure 1, I provide in the side of aperture 77 through whichthe 'upper end of lever 75 eXtends,'three slots 80, 81 and 82 in whichthe upper end of lever 75 may be positioned to secure it in a selectedone of three positions. v

lVhen the upper end of lever 75 is moved towards roll 8, the shaft 69will be moved outwardly in shaft 7 to bring the pins 71, 72 intoregistration with aperture 65 in gear 64, thus locking gear 64 to shaft7.

Similarly, when the upper end of 'shaft 75 is moved away from roll 8,the farthest extent possible, the shaft 69 will be moved inwardly inshaft 7 to bring the pins 71 and 7 2 into registration with apertures 63in gear 62 so that gear 62 will become locked to shaft 7.

If it is desired to leave roll 8 at rest, the upper end of shaft 75 isplaced in notch 8l which will hold member 70 in a posit-i on where thepins 71 and 72 will not be in registration J with either aperture 63 orlaperture 65.

It will be understood that when the upper end .of lever 75 is moved tobring pins'71 and 72 into registration with aperture 63, the upper endof lever 75 will be placed in slot 82 to lock it in position."

Similarly, when the upper end of lever 75- a's bv a pin 83, a crank 84having opposed jaws 85 and 86 which encircle the cam member 41.

The rotary movement of member 40 on which is eccentricallymounted thecam member 41 will cause the crank 84 to be oscillated and thisoscillating movement will be communicated to the shaft 20 upon which ismounted the ironer shoe support 22.

The oscillating movement of shaft 20 will cause the shoe to be movedinto and out of contact with the roll 8.

In order to perform the ironing operation properly, it is necessary thatthe shoe 25 be held in Contact with the roll 8 under some degree ofpressure.l

In order to accomplish this result in the simplest way, the shaft 20 ismade of a material which is sufficiently tortionally resilient' as vtobecome slightly distorted when the shoe 25 moves into contact with theroll 8 and thus through its inherent resiliency exert a certain degreeof pressure by the shoe 25 against the roll 8.

The relation of parts is such that when the member 50 is in the path ofmovement of the plate 46, the clutch member 40 will come to rest withthe highl side of the cam 41 in either the extreme low -position or theextreme high position depending upon which end of plate 46 contacts'withmember 50.

When the high side of cam 41 is in the down position, the crank 84 willalso be in the down position and the shaft 20 will be in a position tohold the shoe 25 under pressure contact with the roll 8.

When the parts are in this position, the key 39 on shaft 28 will be inregistration with the low side of the cam surface 31 on bearing memberso that gear 54 will be in clutching relation with gear so that the roll8 may be rotated in either direction by manipulation of the lever 75.

When the clutch member comes to rest with the high side of the cam 41 inthe raised position, -the crank 84 will also be `in the raised positionand the shaft 20 will be in such a position that the shoe 25 will be outof engagement with the roll 8.

When the parts are in this position, the key 39 will be in registrationwith the high side of cam surface 31 and the gear 54 will have beendisengaged from gear 35 due to the axial movement of the shaft 28 andthe roll 8 can be rotated by hand.

It will thus be seen that by the manipulation of handle 52 to rock shaft51, the member may be moved into and out of the path .of movement ofplate 46 at the will o f the operator. It Will also be seen that theroll 8 may be caused to rotate in either direction by the manipulationof lever 75 or, if desired, the lever 75 may be positioned so 5 that theclutch member 70 is out of engagement with both gear 62 and gear 64 sothat the roll 8 Will be at rest While the shoe 25 moves into and out ofpressure contact With roll 8. This relation of parts is particularlyconvenient When it is desired to perform a pressing operation on anarticle. I For the purpose of controlling the operation of the motor 32,I provide in casing 2 a switch 87.

I have here described a particular type of ironing machine and operatingmechanism therefor, but it will be understood that my invention may beused in combination with other types of operating mechanism in order toobtain a structure in which the di rection of rotation of the roll maybe varied as desired or the roll may be left at rest while the remainderof the mechanism operates.

g5 It will also be understood that numerous changes in the size,relation and arrangement of parts may be made Without departing from thespirit of my invention for although I have shown and described aspeeificstruc- 30` ture and form and relation of parts as anexempliication of an embodiment of my in- Vention, I do not desire torestrict myself to the exact size, shape or arrangement of parts, asvarious changes may be made Within the 65 scope of the appended claim.

I claim:

In an ironing machine, in combination, a roll, a single drive shaft forthe roll, a shoe adapted to be moved into and out of pres- 0 surecontact with the roll, means for operating the shoe, said drive shaftprojecting from one end of the roll, a casing into which the projectingsh aft end extends` and mechanism confined Within the casing forrotating and 45, controlling the direction of rotation of the shaft androll including spaced gears rotatl ably mounted on the shaft end, aclutch mem- .-f i
